Recently a simple phenomenological model has been proposed to describe the available lattice data for the renormalized Polyakov loop in the deconfinement phase (hep-ph/0505215). These data exhibit unequivocal inverse power temperature corrections driven by a dimension two gluon condensate. The heavy quark free energy is also studied and compared to lattice data.Talk given at Quark Matter 2005, 18th Internationl Conference on Nucleus-Nucleus Interactions, August 4-9, 2005, Budapest, Hungary, 4 pages, 3 figuresHigh Energy Physics - Phenomenologytext
